Abstract: PROBLEM TO BE SOLVED: To suppress disturbance of air flow in the vicinity of a suction port of an impeller by constituting at least one of a locking means fixing a rear face shroud to a rotary shaft or the rotary shaft so as to project to an opposite side of an electric motor of the suction port. SOLUTION: A rear face shroud 31 is held on a rotary shaft 37 of an electric motor by a first spacer 38, a washer 39, a pressing plate 40 and a second spacer 41 and a locking means 42 such as a nut is tightened and fixed on a screw part 43 provided at a tip part of the rotary shaft 37. A tip part 42a on an opposite side to an electric motor of the locking means 42 is projected to the opposite side to the electric motor of an opening location of a suction port 32a.  Air flow flows from wide space into a suction port of a casing 48 and narrow space of the suction port 32a of an impeller 30 by an operation of the electric motor, but because the locking means 42 within the suction port 32a is projected from the suction port 32a of the impeller 30, air flow is straightened up to some degrees at a point of time when air flow passes the suction port 32a, disturbance of air flow is suppressed and a rise in pressure and inside flow are smoothly performed.

IPC: G03B17/00
Filed: 1988-08-16
Abstract: PURPOSE:To always switch deceleration ratio under appropriate conditions by making a reference value for switching the deceleration ratio of a film winding mechanism in the use of a camera alone different from a reference value for switching the reduction ratio of the film winding mechanism in the use of a motor driving device. CONSTITUTION:In winding a film with the motor driving device MD mounted on the camera B, the deceleration ratio of variable speed power transmission mechanisms K2 and K3 in the camera B is switched to a low speed level when film moving speed is equal to or higher than a first value V1. In winding a film with the camera B alone, the deceleration ratio of a variable speed power transmission mechanism K1 is switched to the low speed level when the film moving speed is higher than or equal to a second value V2 (V1>V2). Thus, the deceleration ratios of the variable speed power transmission mechanisms K1-K3 are appropriately switched according to various phenomena.

Title: Call signal sending system
Inventor: FUJISAWA MASATO
IPC: H04M3/02
Filed: 1981-12-18
Abstract: PURPOSE:To eliminate bad influences to adjacently installed circuits of other subscribers at the time of sending a call signal, by sending the call signal to the telephone set of a subscriber from the midpoint of the primary winding of a repeating coil through the primary winding. CONSTITUTION:A call signal is sent to a line A of a subscriber's line L1 through  a contact (r) provided between the midpoint N1 of a repeating coil TR1 and a  resistance R1 and the primary winding of the TR1. Therefore, a transient voltage generated when the call signal is interrupted intermittently by the contact (r) at the time of sending the call signal, is attenuated by the inductance of the primary winding of the TR1, and induced noises to adjacent subscriber's circuits are sharply reduced. Moreover, since the line A side is also earthed through a resistance 3 and a call signal source RG, the degree of unbalance against the ground of the subscriber's circuit sending the call signal is sharply improved, and the induction of the high voltage and transient voltage sent from the subscriber's circuit to a subscriber's line L2 is also improved.

Filed: 1993-08-19
Abstract: PURPOSE: To miniaturize, to raise productivity and to speed-up reaction by placing a film on an edge portion of a supporting body as a frame of single crystal silicon. CONSTITUTION: A sensor comprises a film 2 and a frame 1, and the film 2 is, at its edge part, connected to the frame 1. The film 2 is provided with temperature measurement elements 3 and 4. The element 3 is a temperature dependent resistor, and through a connection part 6 on the frame 1, measures the electric resistance of the element 3. The element 4 is constituted as a thermal element, comprising members 10 and 11 of different materials, and if migration area between materials is held at various temperatures, the connection part 6 is causing thermal stress. The film 2 is very thin, so it promptly receives the temperature of medium which is flowing ahead of it. Thus, with the elements 3 and 4, the temperature of medium which is flowing a head of it is promptly measured.  In order to keep delay time caused by temperature stress short, the material suitable for the film 2 is silicon oxide or silicon nitride, and they can be obtained with ease on a silicon surface. Thus, reaction speed of sensor rises too.
